Hi,

Currently you can change this via the OnBeforeStart event where you get access to the video constraint objects that is sent to the camera device request.

procedure TForm3.WebCamera1BeforeStart(Sender: TObject;
  var AConstraints: TJSObjectRecord);
begin
  //Request the resolution to be at 1920x1080 if possible by using 'ideal'
  //Use 'min' and 'max' to set the minimum or maximum resolution instead
  AConstraints.jsobject.Properties['width'] := new(['ideal', 1920]);
  AConstraints.jsobject.Properties['height'] := new(['ideal', 1080]);
end;

You can read more about constraints here.
